When gasoline consumption of conventional internal combustion engine (ICE) vehicles is compared with similar sized plug-in vehicles operating on electricity, plug-in vehicles on the road displaced 216 million gallons of gasoline in 2017, according to the US Energy Information Administration (EIA). Gasoline displacement from plug-in vehicles is about 39% more than it was in 2016 and about twice as much as 2015.

The gasoline displacement from BEVs versus PHEVs was split almost evenly in 2012 and 2013 but BEVs accounted for 60% of the gasoline displacement by 2017.
